AAT4285 12V Slew Rate Controller Load Switch

The AAT4285 SmartSwitch is a P-channel MOSFET power switch designed for high-side load switching applications. The MOSFET operates from a 3.0V to 13.2V input range making it ideal for applications in single or dual cell Lithium-Ion battery systems. The device has a typical RDS(ON) of 240mΩ at 12V, allowing a low forward voltage drop and high current handling.

Features

fast load switch turn-on capability of 100μs and offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. The quiescent supply current is very low, typically 25μA. The AAT4285 is available in a Pb-free, 8-pin SC70JW package and is specified over the -40°C to +85°C temperature range.
